Correas de distribución HTD are organized here by the selection variables an engineer or buyer actually needs: profile, tooth count, belt width, shaft interface and construction. Matching HTD timing belts for 3M, 5M, 8M and 14M pulley systems.
Cómo navegar por esta familia de productos
Comience con la designación completa de la correa. Luego, identifique el número de dientes o la relación de velocidad requerida, el ancho de la cara de la correa y la disposición del eje/montaje. No seleccione basándose únicamente en el diámetro exterior. Si se trata de un reemplazo, registre la proyección del cubo y la disposición de la brida desde ambos lados antes de comparar los productos.
Las fichas de producto que aparecen a continuación enlazan con páginas detalladas que incluyen tablas de catálogo, referencias de dimensiones y guías para solicitudes de presupuesto. Utilice la cuadrícula de productos que aparece más abajo para acceder a las páginas de producto detalladas y comparar las configuraciones de catálogo disponibles para esta familia.

Configuration Review
Use the mating belt and machine interface as the controlling inputs. Where a standard product does not fit the shaft or axial envelope, provide a drawing rather than adapting unrelated dimensions from several parts.

Comprobaciones de compatibilidad y medición
Antes de realizar el pedido, confirme el sistema de dientes, el número de dientes, el ancho de trabajo, el diámetro del orificio/casquillo, la proyección del cubo, la disposición de la brida y la ubicación de la línea de la correa. Registre en el plano cualquier requisito crítico de ajuste o excentricidad. Para proyectos de reemplazo, inspeccione la polea existente para detectar desgaste que pueda distorsionar las mediciones y verifique si se ha modificado la disposición del eje o del espaciador.

Belt Identification Before a Matching Pulley Is Quoted
When the belt marking is readable, preserve the complete designation in the enquiry rather than reducing it to only the pitch number. Width and family identification help keep the belt-side decision separate from the pulley shaft interface.
If the belt is damaged or the marking is unclear, send photographs and the existing pulley information together. A replacement set should be confirmed from the complete drive record rather than from visual similarity alone.
HTD Timing Belts FAQ
¿Qué información se necesita para obtener un presupuesto?
Envíe la correa/perfil, los dientes, el ancho de la correa, los detalles del eje o buje, la cantidad y el destino. Incluya un dibujo para cubos, bridas, materiales, acabados o requisitos de inspección no estándar.
¿Es posible identificar una polea antigua a partir de una fotografía?
Una fotografía ayuda a identificar la construcción, pero se necesitan las dimensiones y la marca de la correa correspondiente antes de poder confirmar un reemplazo.
¿Son intercambiables todas las poleas con el mismo paso nominal?
No. Confirme la familia de dientes y la interfaz mecánica exactas. El paso nominal por sí solo no es suficiente para decidir si se debe reemplazar el diente.
Match the Belt and Pulley Before Finalizing the Order
Use the complete belt marking to identify the HTD family and working width before choosing a pulley row. A shared pitch number is not a substitute for confirming the intended tooth family, especially when legacy or neighboring curvilinear profiles are involved.
For replacements, inspect both belt and pulley wear. Edge damage, flange polishing or uneven tooth contact can point to alignment or shaft-position problems that should be corrected rather than copied into a new set of components.
The Belt Is the First Compatibility Check
A synchronous pulley cannot be selected safely from pitch diameter alone. Start with the complete belt designation and confirm the HTD pitch family, then confirm belt width. The pulley tooth count establishes the speed relationship and physical size, while the shaft interface determines how the selected pulley is installed. A belt with the same nominal pitch number but a different tooth system should not be assumed compatible.
For replacement work, keep the old belt and pulley information together until the family is confirmed. If the belt marking has disappeared, tooth count, pitch-related measurements, width and clear tooth-profile photographs are more useful than a guess based on outside diameter.
Matching Sequence
- Read the complete belt marking and identify the HTD family.
- Record belt width and the tooth counts of driver and driven pulleys.
- Confirm the product-series width and construction in the pulley catalogue.
- Check center distance, belt line, shaft interfaces and installation access.
- Release the exact pulley row or drawing together with the matching belt reference.
When a new drive is being designed, provide speed relationship, duty and center distance so the belt and pulley arrangement can be reviewed as one system.

What Not to Infer From a Belt Code
The belt family helps identify the tooth geometry, but it does not define the pulley bore, hub, flange or material. Those remain pulley-selection decisions. Likewise, a pulley product code does not by itself confirm belt length or the installed center distance. Keep component identity and system geometry as separate checks.
Replacement Belt Data Should Stay With the Pulley Record
When maintenance teams replace belts and pulleys at different times, product identity can be lost. Store the accepted belt family, width, pulley tooth counts and center-distance reference together in the maintenance record. If a belt construction changes, review tensioning and application requirements rather than assuming the previous installation settings carry over unchanged.
For an RFQ, send the belt marking exactly as printed when it is legible. Avoid shortening the designation to pitch alone because the omitted family or width information may be the part that distinguishes the compatible pulley.
Keep Drive Records Complete After Installation
Store the installed belt code, pulley tooth counts and width-series information with the machine documentation. If the drive is retensioned or a belt construction changes during maintenance, note the change and review the relevant installation guidance. A future buyer should be able to identify both mating components without dismantling the machine.
When ordering a belt and pulley together, put both references on the same RFQ. That allows the pitch family and working width to be checked as a pair while the pulley shaft interface remains a separate, explicit requirement.
